Low-temperature Vacuum Double Effect Falling Film Evaporator

Double Effect falling film evaporator is made of two single effect falling film evaporator in series together, double effect falling film evaporator is the primary effect evaporator produced by the secondary steam as a heating source, introduced into another evaporator, as long as the pressure and melting boiling point in the evaporator are controlled, so that it is properly reduced, the secondary steam generated by the single-effect evaporator can be heated After the material is added by the upper part of the heating chamber, it is distributed by the liquid distributor and then flows down the tube in a film shape to be heated and vaporized. The vaporized steam and liquid are drawn out from the lower end of the heating tube together, and the concentrated liquid is obtained after the separation of gas and liquid Due to the short residence time of the material and high heat transfer coefficient, it is generally used to deal with heat-sensitive materials, and can also be used for materials with large evaporation viscosity, but it is not suitable to deal with the easy crystallization of the solution.
Double-effect falling film evaporator in the industry, which is mostly suitable for milk glucose starch xylose pharmaceutical, chemical, biological engineering, environmental protection engineering and other industries.
